Package description
The @babel/plugin-transform-regenerator package is a Babel plugin that enables the transformation of generator functions and async functions into ES5-compatible JavaScript code using the regenerator runtime. It allows developers to use these modern features in environments that do not natively support them.
Transformation of generator functions
This plugin transforms generator functions into ES5 code by converting the generator syntax into a state machine that is compatible with older JavaScript engines.
function* gen() { yield 1; yield 2; yield 3; }Transformation of async functions
It also transforms async functions into generator functions and then applies the generator function transformation to ensure compatibility with environments that do not support async/await syntax.
async function foo() { await someAsyncFunction(); }The regenerator-runtime package provides the runtime needed to support the generator functions in environments that do not natively support them. It is often used in conjunction with @babel/plugin-transform-regenerator, which handles the syntax transformation.
This package is similar to @babel/plugin-transform-regenerator in that it transforms async functions into generator functions. However, it focuses solely on async functions and does not handle generator functions.
fast-async is a Babel plugin that transforms async/await functions into ES5-compatible code using Promises instead of generators. It provides an alternative approach to handling async functions and can be faster than regenerator-based transformations.
